Debiting account for cancelled deal

<p>I initially showed interest in a Telkom mobile product that will allow me to have wifi at home. This device was delivered early 0n 11 November 2016. I then decided that i dont want this product and immediately informed Telkom. The device was collected at my house during November 2016. Submitted cancellation form all before end November 2016. Yet at the end of December 2016 my account was debited by an amount just over R 1300.00. How did this happen when i am not even using the product. I reversed the debit order and assumed it was a mistake since i cancelled over a month before. But again my accoun has been debited on the 13 Jan 2017 by an amount of R 2000.00. Can someone tell me what is going here, something is not right here but i am receiving very little response from Telkom</p>
